[SCSI] lpfc: avoid double-free during PCI error failure

If a PCI error is detected that cannot be recovered from, there
will be a double call of lpfc_pci_remove_one(), with the second call
resulting in a null-pointer dereference. The first call occurs in
lpfc_io_error_detected(), and the second call during pci device
remove. This patch eliminates the first call; its un-needed.
